Application filed september 6, 1924, Serial No. '736,30'5. ReneWedAugust 20, 1927.

My .invention relates to improvements in brooms, and particularly inhrooms having remorahle handles broom With remo able handle isadvantageous for several reasens; one reason is that either the handleon the brush may be replaced When broken or 'Worn out, Without thenecessity ot' discardng the Whole; another reason' is that the separatedparts may he packed in quantity :for shipment with substantial economyof cost and of space.

A broom embodying my invention is illustrated in the acconipanyingdrawingsfi Fig. a View ot the broom in side elevation; F II is a.:tragmentary 'view to larger Scale, in medial Vertical section; Fig. IIIis a view in transrerse section, on the plane indicated by the lineIII-IIL Fig. II. Fgs. IV, V, and VI are Views in perspective of certainparts detached. The succession of these three figures on the sheet is inthe order of assembly. i

The broom structure includes essentially the brush l, the handle 2, andthe keeper 3. rddtionally a shield 4; is conveniently ncluded, Whichserves to conceal structural'details and to present a better appearance,and to afford an advertising surface.

The brush 1 is of usual construction, consistin of a sewn sheat ofbroom-corn, properly shaped and trimmed. The butt-end of the sheaf ishowever capped and encased in a metal shoe 11 (formed ordinarly of sheetsteel), riveted to the sheaf as indicated at 12. A central orifice isformed in shoe 11, and. surrounding this orifice is an inWardly eX-tending, screW-threaded ferrule 13. This ferrule 13 is preferably formedas a separate piece With flanged base, by Which it may be permanentlyunited to the Web of metal Which forms the adjacent part of the shoe 11.The ferrule is preferably formed from sheet steel by stamping andthread-rolling. In Figs. II and VI an engagement of tongues 14: cut fromand inturned from the substance of shoe ll upon the edge of the basefiange of ferrule 13, is shown This is itself not preferably theefiective means of unon of these parts; it is merely the means ofinitial as sembly, and is preterably 'followed by spot- Welding betweenthe surfaces so assembled in contact.

In the building of the brush a central space s left extending inward inthe aXial line of the terrule 13 When applied, a space such as to alloWthe seated handle 2 (presently to be described) to extend through the*ferrule and inwardto the Zone of sewing A as indicated in Fi II.

The butt-end of the brush, beneath the shoe 11, and the* surtaces' ofbroom-corn spread apart to tonn within the brush a space for theentrance of the handle as described, are in the course TO rabrication,preterably coated With pitch.

The shoe 11 s split at its ends, as indip a screW-threaded band, adaptedto engage the sCreW-threaded fel-rule 13, already *described. Thusadjacent the screW-threaded band a tapered surtace is *found forpurposes presently to *be 'descrihecl. The construction in thisparticul'ar is clearly shown in Fig. II. When the handle is in place andseatcd and secured by the screW-threaded engagement here alluded to, thepointed end of the handle Will extend Within the brush to the Zone ofsewing A. This inward extension of the handle Within the brush alordsStrength, particularly Strength to resist the strain of service. v

The keeper 3, formed also, preferably, as a stamping of sheet steel, isshaped to fit snugly upon the shod butt-cnd of the brush, to be archedover the shoulders of the brush member leaving open Spaces 33 On eitherside, and by its fiaring ends 31 to make Wedging engagement upon thesloping shoulders 16 of the brush. The keeper is provided with a centralOrifice around Which the metal web of the keeper 3 is crowned, as isindcated in the upWardly curved tapering rim 32. n

WVhen the parts are assembled, asshoWn in Fig. II, the Crown 32 Whichsurrounds the orifice in the keeper is engaged hy the conical surface ofthe terrule 21 of the handle, and the screwing of the handle home placesthe keeper 3 under strain: the flarng ends 31 of the keeper engaging thesloping shoulders 16 of the brush, yieldingly resist ,idle memberapplied upon the shod end of the brush l, and interposed between thebrush l and the heeper 3, and clamped to place beneath the keeper. Theshield t enn- 'sists merely O' opposite plates united by bridging Web orWebs 41. It is freely expansible, to shape itself to the butt-end ot thebrush. Allowance is of Course made in the proportioning of' the otherparts, for the resence of thls shield member t.

The shield member When in place covers and ooneeals the cheeks of theshoe ill, through Which riveting has been made, and, exposed Within theSpaces ::33 of the heeper, presents *fair smooth surfaees at theseDoins. These fair smooth surfaees are oil* course available foradvertising purposes.

The exposed met-al surt'aces may be coated,

eolored, and decorated as desired.

I claim as my invention.

1. In a broom the combination of a brush member provided with slopingshoulders and With a sereW-threaded bore extending in- Ward from itshatt-end, a handle provided at an interval from its tip With aserewthreaded band and, adjacent such band, with 35 a ta aered surface,and seated in the bore in the rush member, its screw-thieaded bandengaging the screW thread of such bore, and its tip extending inWardheyond such region of engagement and into the body ol' the brush member,and a keeper of spring metal with Hal-ing' ends and with medial andcrowned orifice overlying the butt-end of the brush member andsurrounding the tapered surtace of the handle introduced Within the boreof the brush member, and engaged ai its crowned orifice by the handleand engagiun at its ends and under tension the shoulders ot the brushmember while the handle, ntroduced into the bore within the brush memberremote from Screwed-humm position, said keeper, 'when the handle isScrewed home in the brush member, being held under tension betweensuri'aces Which :it engages upon the shouldcrs of the ln'ush and uponthe taper of the handle.

In a broom the combination ozl' a brush member enc'ased at its hatt-endin a sheetmetal shoe riveted to place upon it, said shoe beina' providedWith a screw-threaded bore. a sm'ew-tbreadcd handle removabl seated insaid bore, an arehed heeper overlying the shoulders of the brush memberand sm rounding the handle when introduced in the bore of said brushn'lember, and a shield interposed between the brush memhe' and thelceepcr and overlying the riveted sides of the shoe, otherwise exposedWithin the arch of the keeper.

In testimony Whereof I have hereunto set my hand.
